User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Scope Guard

This command's own work is limited to updating the project constitution itself. Dependent templates and commands read the constitution at runtime and are not modified here.

• Classify every part of the user input as either constitution content or a separate, non-governance intent.
• If the input includes feature implementation, code generation, refactoring, building, or deployment requests, you MUST NOT execute them. Extract them as deferred intents instead.
• You MUST NOT create, modify, or delete application source files, feature routes, components, tests, deployment files, or other artifacts unrelated to the constitution workflow.
• If it is unclear whether an instruction is constitution content, ask for clarification before making changes.
• After completing the constitution update, include a Next Actions section for each deferred intent. List the original intent and suggest the appropriate follow-up Spec Kit command, such as $speckit-specify, without invoking it.
• If there are no non-governance intents, omit the Next Actions section.

Pre-Execution Checks

Check for extension hooks (before constitution update):

• Check if .specify/extensions.yml exists in the project root.
• If it exists, read it and look for entries under the hooks.before_constitution key
• If the YAML cannot be parsed or is invalid, skip hook checking silently and continue normally
• Filter out hooks where enabled is explicitly false. Treat hooks without an enabled field as enabled by default.
• For each remaining hook, do not attempt to interpret or evaluate hook condition expressions:
  • If the hook has no condition field, or it is null/empty, treat the hook as executable
  • If the hook defines a non-empty condition, skip the hook and leave condition evaluation to the HookExecutor implementation
• When constructing command invocations from hook command names, replace dots (.) with hyphens (-). For example, speckit.git.commit → $speckit-git-commit.
• For each executable hook, output the following based on its optional flag:
  • Optional hook (optional: true):

    ## Extension Hooks
    
    **Optional Pre-Hook**: {extension}
    Command: `/{command}`
    Description: {description}
    
    Prompt: {prompt}
    To execute: `/{command}`
    

  • Mandatory hook (optional: false):

    ## Extension Hooks
    
    **Automatic Pre-Hook**: {extension}
    Executing: `/{command}`
    EXECUTE_COMMAND: {command}
    
    Wait for the result of the hook command before proceeding to the Outline.
    

    After emitting the block above you MUST actually invoke the hook and wait for it to finish before continuing. Run it the same way you would run the command yourself in this agent/session (the invocation may differ from the literal {command} id shown above, e.g. a skills-mode agent runs it as /skill:speckit-... or $speckit-...). Emitting the block alone does not run the hook.
• If no hooks are registered or .specify/extensions.yml does not exist, skip silently
